Product Information

This is to prevent dangerous light bulbs from being used in light fixtures that aren’t designed for them. As a result, LED light bulbs have become increasingly popular and are therefore available across a wide range of styles, cap fittings, lumens and wattages.

They are included in the IEC standard "IEC 60061 Lamp caps and holders together with gauges for the control of interchangeability and safety".This is why light bulb bases aren’t standardized: if they were interchangeable across light fixtures, people would risk inserting a light bulb into sockets that weren’t designed for them.

If these safety risks don’t concern you, then by all means go for it – but be sure to read the fine print on the light bulb packaging. Often referred to by the industry term of lamps, choosing the correct bulb helps to ensure optimum performance, efficiency and lifespan for both practical and decorative use. A lowercase "q" at the end of the designation indicates that it is a quad-pin base, with two bi-pin pairs. The bulbs have metal bases (caps) that are threaded in the right direction and screwed into matching threaded sockets (lamp holders). You can simply replace your existing lamps or upgrade to the latest versions if you're feeling green.For example, a bi-pin base is commonly used for halogen and LED lamps, while a double contact base is used for fluorescent lamps. Luckily, there are standards for light bulb base sizes in the lighting industry, and parts are made to meet those standards. In the early days of electricity, the only standard connector was an Edison screw, and all appliances except light bulbs were hooked up to AC power through lamp sockets.

Capsule bulbs are commonly used in kitchens, display cabinets, chandeliers, pendants, and other fixtures that require a small, low-profile bulb. Bulbs with these bases are commonly used for appliance lights, such as microwave lights, refrigerator lights, and range hood lights.

This design allows the connection to be made and broken quickly and easily, while also providing a secure connection. Bayonet bases are a type of electrical connector that uses a bayonet-style locking mechanism to secure the connection.
